IBM HTTP Server up to 1.3.28x Transfer-Encoding HTTP Request cross site scripting

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as problematic, was found in IBM HTTP Server up to 1.3.28x (Web Server). This affects an unknown code block of the component Transfer-Encoding Handler. The manipulation as part of a HTTP Request leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-80. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. This is going to have an impact on integrity. The summary by CVE is:

The Apache HTTP server before 1.3.34, and 2.0.x before 2.0.55, when acting as an HTTP proxy, allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes Apache to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling."

The weakness was shared 10/24/2005 by Watchfire with IBM (Website). It is possible to read the advisory at www-1.ibm.com. This vulnerability is uniquely identified as CVE-2005-2088 since 06/30/2005. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but an exploit is available. The attack technique deployed by this issue is T1059.007 according to MITRE ATT&CK.

After even before and not, there has been an exploit disclosed. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 29 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21113 (HP-UX PHSS_34204 : HP-UX VirtualVault running Apache 1.3.X Remote Unauthorized Access (HPSBUX02101 SSRT051128 rev.1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family HP-UX Local Security Checks and running in the context l.
